Prerequisites

Before starting with the installation, make sure that you have the following:

A FreeBSD Latest operating system installed on your computer
A sudo user account with root privileges
An active network connection

Step 1: Installing Required Dependencies

Firstly, you need to install the required dependencies for Mailman by running the following command:

sudo pkg install py36-virtualenv py36-cryptography

This command will install the Python virtual environment and cryptography libraries, which are necessary for the installation of Mailman.

Step 2: Create Mailman User

To run Mailman, we need to create a dedicated user account. Run the following command to create the Mailman user:

sudo pw useradd mailman -g mailman -d /usr/local/mailman -s /sbin/nologin

This command will create a user account named mailman with the home directory /usr/local/mailman.

Step 3: Install Mailman

Now that we have installed the required dependencies and created a dedicated user account, we can proceed with the installation of Mailman.

Download Mailman's latest source code from the official website - https://www.gnu.org/software/mailman/download.html.
Extract the downloaded archive using the command below:
```
sudo tar -xzvf mailman-2.1.34.tgz
```
Replace mailman-2.1.34.tgz with the latest version of Mailman.
Move the extracted Mailman directory to /usr/local/share/mailman using the command below:
```
sudo mv mailman-2.1.34 /usr/local/share/mailman
```
Switch to the mailman user account by running the command:
```
sudo su - mailman
```
Create a virtual environment for Mailman by running:
```
virtualenv mailman
```
Activate the virtual environment by running:
```
source mailman/bin/activate
```
Install Mailman requirements by running:
```
sudo python setup.py install
```
Follow the prompts to complete the installation.

After the installation is complete, you can deactivate the virtual environment by running:

deactivate

Step 4: Configure Mailman

Now that we have installed Mailman, it is time to configure it to work properly.

Switch to root user account by running the following command:
```
exit
```
Open the file /usr/local/mailman/Mailman/mm_cfg.py using a text editor:
```
sudo vim /usr/local/mailman/Mailman/mm_cfg.py
```
Uncomment the line that specifies the MTA option and set it to Postfix.
```
MTA = 'Postfix'
```
Save and close the file.

Step 5: Start Mailman

Start the Mailman service by running the following command:

sudo /usr/local/mailman/bin/mailmanctl start
